WindowsProcessStats (Statistics on a Microsoft Window's process.)

Statistic

Description

handles

The total number of handles currently open by this process. This number is the sum of the handles currently open by each thread in this process.

priorityBase

The current base priority of the process. Threads within a process can raise and lower their own base priority relative to the process's base priority

threads

Number of threads currently active in this process. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread.

activeTime

The elapsed time in milliseconds that all of the threads of this process used the processor to execute instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

pageFaults

The total number of Page Faults by the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This will not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared.

pageFileSize

The current number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and lack of space in paging files can prevent other processes from allocating memory.

pageFileSizePeak

The maximum number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and lack of space in paging files can prevent other processes from allocating memory.

privateSize

The current number of bytes this process has allocated that cannot be shared with other processes.

systemTime

The elapsed time in milliseconds that the threads of the process have spent executing code in privileged mode. When a Windows system service is called, the service will often run in Privileged Mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.

userTime

The elapsed time in milliseconds that this process's threads have spent executing code in user mode. Applications, environment subsystems, and integral subsystems execute in user mode. Code executing in User Mode cannot damage the integrity of the Windows Executive, Kernel, and device drivers. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.

virtualSize

Virtual Bytes is the current size in bytes of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and by using too much, the process can limit its ability to load libraries.

virtualSizePeak

The maximum number of bytes of virtual address space the process has used at any one time. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is however finite, and by using too much, the process might limit its ability to load libraries.

workingSetSize

The current number of bytes in the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before they are paged out out to disk.

workingSetSizePeak

The maximum number of bytes in the Working Set of this process at any point in time. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before they leave main memory.

WindowsSystemStats (Statistics on a Microsoft Windows machine.)

Statistic

Description

committedMemoryInUse

This represents the percentage of available virtual memory in use. This is an instantaneous value, not an average.

events

The number of events in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. An event is used when two or more threads wish to synchronize execution.

interrupts

The total number of harware interrupts on the computer. Some devices that may generate interrupts are the system timer, the mouse, data communication lines, network interface cards and other peripheral devices. This counter provides an indication of how busy these devices are on a computer-wide basis.

mutexes

The number of mutexes in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Mutexes are used by threads to assure only one thread is executing some section of code.

processes

The number of processes in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. Each process represents the running of a program.

processorQueueLength

The instantaneous length of the processor queue in units of threads. All processors use a single queue in which threads wait for processor cycles. This length does not include the threads that are currently executing. A sustained processor queue length greater than two generally indicates processor congestion. This is an instantaneous count, not an average over the time interval

registryQuotaInUse

The percentage of the Total Registry Quota Allowed currently in use by the system.

sharedMemorySections

The number of sections in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. A section is a portion of virtual memory created by a process for storing data. A process may share sections with other processes.

semaphores

The number of semaphores in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. Threads use semaphores to obtain exclusive access to data structures that they share with other threads.

threads

The number of threads in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. A thread is the basic executable entity that can execute instructions in a processor.

dgramsReceived

The number of datagrams received on the VM's machine.

dgramsNoPort

The number of incoming datagrams that were discarded due to invalid headers

dgramsReceivedErrors

The number of received UDP datagrams that could not be delivered for reasons other than the lack of an application at the destination port

dgramsSent

The number of datagrams sent on the VM's machine

loopbackPackets

The number of packets sent/received on the loopback interface

loopbackBytes

The number of bytes sent/received on the loopback interface

netPacketsReceived

The number of network packets received (total excluding loopback)

netBytesReceived

The number of network bytes received (total excluding loopback)

netPacketsSent

The number of network packets sent (total excluding loopback)

netBytesSent

The number of network bytes sent (total excluding loopback)

availableMemory

The size, in bytes, of the virtual memory currently on the Zeroed, Free, and Standby lists. Zeroed and Free memory is ready for use, with Zeroed memory cleared to zeros. Standby memory is memory removed from a process's Working Set but still available. Notice that this is an instantaneous count, not an average over the time interval.

cacheFaults

Incremented whenever the Cache manager does not find a file's page in the immediate Cache and must ask the memory manager to locate the page elsewhere in memory or on the disk so that it can be loaded into the immediate Cache.

cacheSize

Measures the number of bytes currently in use by the system Cache. The system Cache is used to buffer data retrieved from disk or LAN. The system Cache uses memory not in use by active processes in the computer.

cacheSizePeak

Measures the maximum number of bytes used by the system Cache. The system Cache is used to buffer data retrieved from disk or LAN. The system Cache uses memory not in use by active processes in the computer.

committedMemory

The size of virtual memory, in bytes, that has been Committed (as opposed to simply reserved). Committed memory must have backing (i.e., disk) storage available, or must be assured never to need disk storage (because main memory is large enough to hold it.) Notice that this is an instantaneous count, not an average over the time interval.

committedMemoryLimit

The size, in bytes, of virtual memory that can be committed without having to extend the paging file(s). If the paging file(s) can be extended, this is a soft limit. Note that this value will change if the paging file is extended.

contextSwitches

The number of times this thread has lost the cpu to another thread. Thread switches can occur either inside of a single process or across processes. A thread switch may be caused either by one thread asking another for information, or by a thread being preempted by another, higher priority thread becoming ready to run. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of User and Privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows on behalf of an application may appear in other subsystem processes in addition to the Privileged Time in the application. Switching to the subsystem process causes one Context Switch in the application thread. Switching back causes another Context Switch in the subsystem thread.

demandZeroFaults

The total number of page faults for pages that must be filled with zeros before the fault is satisfied. If the Zeroed list is not empty, the fault can be resolved by removing a page from the Zeroed list.

pageFaults

The total number of Page Faults by the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This will not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared.

pageReads

The number of page read operations done by the process since it was last started. These operations involve actual disk reads and not reads from the shared page cache

pages

The total number of pages read from the disk or written to the disk to resolve memory references to pages that were not in memory at the time of the reference. This is the sum of pagesInput and the pagesOutput. This counter includes paging traffic on behalf of the system Cache to access file data for applications. This value also includes the pages to/from non-cached mapped memory files. This is the primary counter to observe if you are concerned about excessive memory pressure (that is, thrashing), and the excessive paging that may result.

pageWrites

The number of pages written by the process since it was last started. These page writes are actual disk writes and not just writes into the shared page cache. Unless a large data load is in process, the number should be low for all processes except the Stone's AIO page server process.

pagesInput

The total number of pages read from the disk to resolve memory references to pages that were not in memory at the time of the reference. This counter includes paging traffic on behalf of the system Cache to access file data for applications. This is an important counter to observe if you are concerned about excessive memory pressure (that is, thrashing), and the excessive paging that may result

pagesOutput

A count of the total number of pages that are written to disk because the pages have been modified in main memory

systemCalls

The total number of calls to Windows system service routines on the computer. These routines perform all of the basic scheduling and synchronization of activities on the computer, and provide access to non-graphical devices, memory management, and name space management.

cpuActive

The percentage of time spent doing useful work by all processors. On a multi-processor system, if all processors are always busy this is 100%.

cpuIdle

The percentage of time the machine's processors spent idle.

cpuInterrupt

The percentage of time spent receiving and servicing interrupts on all the processors on the machine. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity.

cpuSystem

The percentage of time spent in privileged mode by all processors. On a multi-processor system, if all processors are always in privileged mode this is 100%. When a Windows system service is called, the service will often run in privileged mode in order to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system may be explicit, or they may be implicit such as when a page fault or an interrupt occurs. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows on behalf of an application may appear in other subsystem processes in addition to the cpuSystem in the application process.

cpuUser

The percentage of time spent executing code in user mode on all the processor's on the machine.
